RR not re-booting?

[mr.prick]

i changed my injectors today and after a few minutes of VE updating
for idle, i turned off the car to make some manual changes.
i attempted to re-start the car and it would not fire up.
i felt a hard reset was in order so when i went through the motions,
it seemed to not reboot.
usually i can hear the fuel pump whine for 2 seconds but,
for some odd reason it will whir for a half second.
i feel it is not rebooting.
i have 35PSI with the key on.

Can you use the scanner to clear all the codes? Sounds like Reduced Power Mode. Had that happen a few times.

what is that? {B???}
i can connect/scan + down/upload.
my fuel pump seems to be "stuck",
when normally rebooting you will here the fuel pump make a whirring sound
when turning the key to the on position in starts to "whir" but gets cut short.
know what i mean?
i am leaning toward my fuel pump now,
but i don`t see why that would crap out after a simple injector swap
and was up and running immediately after the new injectors were installed.
but the fact that my fuel pump seems to be "choking" while the ignition is
turned on points me that way.
other wise i am going to install my stock ECU in the morning and
see what happens.

I would click on the "red engine" in the scanner software and see which DTCs are set. I suspect you are in Reduced Power Mode. If you have not, just clear all DTCs especially since you are still able to read/write the RR

Try checking {G1201} Anti Theft Configuration. This is sometimes a pain on the aussie cars and gives the same symptoms you describe, short fuel pump prime and no start. Try setting it to none. See if that works.

i tried both of these first when this all happened and i`m still not getting
the fuel pump to prime completely.
any more suggestions?

i connected my stock ECU and i have P1626,
and cannot retrieve the tune BUT the fuel pump now cycles.
i cannot retrieve the VIN with the tune.exe and cannot download to it either.
so maybe the BCU is at fault?

[limited cv8r]

In the DVT tab (output control) of the scan tool there is a fuel pump option, you could try activating this just to verify your fuel pump works and you are getting pressure, have you done a full flash of your RR with a known good .tun file, or lastly try your stock PCM.

DTC P1626

<A href="http://127.0.0.1:9001/servlets/BlobShtml?ShtmlFile=705413&pubid=238&evc=sm&cellId =59384#ss1-705413">Circuit Description

The body control module (BCM) produces the theft deterrent fuel enable signal when ignition is ON and the proper key resistor pellet is sensed. The powertrain control module (PCM) monitors the fuel enable signal during crank. If the proper signal is present on the theft deterrent fuel enable circuit, the PCM enables fuel delivery to allow the engine to start. If the PCM detects that the fuel enable signal is not present or incorrect while the engine is running, DTC P1626 will be set. DTC P1626 can cause a no-start condition or normal operation depending on when the loss of the fuel enable signal was detected. The engine will continue to start and run if the condition that set DTC P1626 occurred after the BCM sensed the proper key resistor pellet and signaled the PCM to continue fuel delivery. The engine will start and immediately stall if the condition that set DTC P1626 occurred before the BCM sensed the proper key resistor pellet. With this condition present, the PCM will inhibit fuel delivery and the BCM will disable the starter.

The engine is running.
<A href="http://127.0.0.1:9001/servlets/BlobShtml?ShtmlFile=705413&pubid=238&evc=sm&cellId =59384#ss3-705413">Conditions for Setting the DTC

• The PCM detects an incorrect signal on the theft deterrent fuel enable circuit.
• The condition is present for more than 2 seconds.

<A href="http://127.0.0.1:9001/servlets/BlobShtml?ShtmlFile=705413&pubid=238&evc=sm&cellId =59384#ss4-705413">Action Taken When the DTC Sets

• The PCM will not illuminate the malfunction indicator lamp (MIL).
• The PCM will store conditions which were present when the DTC set as Failure Records data only. This information will not be stored as Freeze Frame data.

• A History DTC will clear after 40 consecutive warm-up cycles have occurred without a malfunction.
• The DTC can be cleared by using a scan tool.

Many situations may lead to an intermittent condition. The following list is to be used as a guide to assist in detecting an intermittent:

• Loose terminal connection. Inspect the harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and faulty terminal to wire connection. Refer to Wiring Systems for diagnosis and repair.
• Damaged harness. Inspect the wiring harness for damage. If the harness inspection does not reveal a problem, observe the display on the scan tool while moving connectors and wiring harnesses related to the sensor. A change in the scan tool display may indicate the location of the fault. Refer to Wiring Systems for diagnosis and repair.
• Inspect the PCM and the engine grounds for clean and secure connections.

okay,
after connecting the stock ECU and recycling the fuel pump but,
not being able to down/upload the tune to it i reconnected the RR
and it started.
i and stumped as why this happened but i won`t look a gift horse in the mouth.
